Npog flux plays lub luag haujlwm tseem ceeb hauv kev lag luam aluminium foundry.Nws txoj haujlwm yog los txo cov roj nkag, tiv thaiv molten aluminium, thiab xyuas kom meej cov txheej txheem casting du.Npog flux muaj qhov nruab nrab melting point, zoo fluidity thiab zoo heev, thiab tau dhau los ua ib feem tseem ceeb ntawm kev tsim cov khoom zoo aluminium.
Ib qho ntawm cov haujlwm tseem ceeb ntawm covnpog fluxyog kom txo tau cov pa roj thaum lub sij hawm casting.Gas inclusions tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg, cuam tshuam nws txoj kev ncaj ncees thiab lub zog.Los ntawm kev siv lub npog flux, qhov saum npoo ntawm molten aluminium tso cai rau txhua qhov gases kom dim tau yooj yim.Qhov no pab tsim cov khoom siv nrog tsawg dua cov teeb meem ntsig txog roj, txhim kho tag nrho cov khoom zoo kawg nkaus.
Lwm qhov tseem ceeb ntawm kev npog flux yog tias nws tuaj yeem tsim cov yeeb yaj kiab ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom.Tom qab melting, tus neeg sawv cev npog nthuav tawm tsis tshua muaj viscosity thiab zoo fluidity, tso cai rau kis tusyees ntawm txhuas nto.Cov zaj duab xis ua raws li kev thaiv, tiv thaiv cov molten aluminium los ntawm oxidized thiab absorbed los ntawm ib puag ncig cua.Los ntawm kev tiv thaiv zoo ntawm txhuas los ntawm cov kev xav tsis zoo, cov flux npog ua kom cov khoom kawg tswj tau qhov zoo tshaj plaws thiab kev ua haujlwm zoo.
Daim ntawv thov kev npog tus neeg saib xyuas yog qhov tseem ceeb tshwj xeeb hauv cov txheej txheem casting ntawm aluminium alloy khoom.Cov alloys feem ntau muaj ntau yam uas cuam tshuam rau lawv cov khoom.Tej zaum qhov tsis zoo ntawm cov ntsiab lus no tuaj yeem txo tau los ntawm kev siv lub npog npog.Cov yeeb yaj kiab tiv thaiv tsim los ntawm tus neeg sawv cev npog tiv thaiv kev tsis xav tau ntawm cov khoom siv txhuas thiab cov alloying.
Ib qho txiaj ntsig tseem ceeb ntawm kev them nyiaj flux yog nws qhov kev siv tsawg thiab tus nqi.Vim nws cov kev pabcuam zoo thiab kev tsim cov yeeb yaj kiab tiv thaiv zoo, nws siv tsawg tsis tsuas yog txo cov khoom pov tseg, tab sis kuj tseem ua rau kev txuag nqi.Aluminium foundries tuaj yeem ua tau zoo dua thiab muaj txiaj ntsig los ntawm kev siv cov flux hauv lawv cov txheej txheem tsim khoom.
Ntxiv nrog rau nws txoj haujlwm thiab daim ntawv thov, cov yam ntxwv ntawm cov khoom npog flux yuav tsum raug txiav txim siab.Thaum xaiv qhov npog flux, nws yog ib qho tseem ceeb uas yuav tau xaiv cov khoom tsim nyog rau koj qhov kev xav tau tshwj xeeb.Tham nrog tus kws tshaj lij hauv thaj chaw los txiav txim siab qhov zoo tshaj plaws npog flux rau koj txoj haujlwm.
Tag nrho cov nyob rau hauv tag nrho cov, npog flux plays lub luag hauj lwm tseem ceeb nyob rau hauv txhuas casting los ntawm kev txo cov roj inflow, tiv thaiv cov molten txhuas thiab ua kom ib tug du casting txheej txheem.Nws txoj haujlwm yog los tsim zaj duab xis tiv thaiv ntom nti nyob rau saum npoo ntawm txhuas kom tiv thaiv oxidation thiab nqus.Nrog rau qhov zoo ntawm kev noj tsawg, tus nqi siab thiab kev sib raug zoo nrog ntau cov khoom siv aluminium, npog flux yog ib qho khoom siv tsis tseem ceeb rau kev tsim cov khoom zoo aluminium.Muab cov ntaub npog flux rau hauv koj cov aluminium casting thiab paub qhov txawv nws ua.
